The automatic answering machine of the present invention is constructed as described above, and its operation will be explained next.

First, the storage operation of the response message sent to the caller will be explained. Response message switch (6)
When the switch is closed, a switching signal is input to the control circuit (10), and the switch circuit (
The output signal of the microphone amplifier circuit (13) is output to the output terminal (16>) of the microphone amplifier circuit (15), and the first

) is applied to the response message memory circuit (17), and the response message memory circuit (17) enters an operating state and also enters a state for performing a write operation. In such a state, when the user speaks a response message into the microphone (12), the signal converted into an electrical signal by the microphone (2) is input to the microphone amplifier circuit (13) and amplified. Ru.

The audio signal amplified by the microphone amplifier circuit (13) is applied to the first audio conversion circuit (21) through the switch circuit (15) and converted into a digital signal. The signal converted into a digital signal by the first voice conversion circuit (21) is sent to the write terminal (17) of the response message memory circuit (17) in the write operation state.
a) and the response message memory circuit (1
7>. In this way, the response message is stored in the response message memory circuit (17>), and the reproduction operation for confirming the response message will be explained.Confirmation reproduction operation of the response message is the response message switch (
6) and the regeneration switch (7). When such an operation is performed, the control circuit (10
), the signal is output to the first output terminal (24) of the switch circuit (23), and the second audio conversion circuit (22) is activated. In addition, the selection terminal (
A signal from the control circuit (1o) is applied to the control terminal (17e) and the control terminal (17c), and the response message memory circuit (17) enters a state for performing a read operation. As a result, the digital signal read from the response message memory circuit (17) is input to the second voice conversion circuit (22) and converted into a voice signal. The signal converted into an audio signal by the second audio conversion circuit (22) is input to the reproduction amplifier circuit (26) through the switch circuit (23), amplified, and then emitted by the speaker (27). . Therefore, the user can reproduce and listen to the response message stored in the response message memory circuit (17), and can confirm the contents of the message.

As described above, the response message storage operation and its reproduction operation are performed. Next, the automatic response operation will be explained.

This operation is performed by closing the automatic response switch (5), and when such an operation is performed, the output signal of the first amplifier circuit (14) is transferred to the output terminal (16) of the switch circuit (15). At the same time, the audio signal from the second audio conversion circuit (22) can be output to the second output terminal (25) of the switch circuit (23). When a calling signal arrives, the receiving circuit (2) to which the signal is input operates, and its output signal is input to the control circuit (10).The control circuit (10) receives the signal from the receiving circuit (2). When the application is permitted, the control circuit (10) outputs a signal that operates the closing circuit (11) and the second voice conversion circuit (22), and a signal that causes the response message memory circuit (17) to read out and operate. is output. When the closing circuit (11) is activated, the closing switch (3) is closed and the telephone line is closed. When the closing circuit (11) is activated, a response message is output. The response message stored as a digital signal in the memory circuit (17) is read out and input to the second voice conversion circuit (22) where it is converted into an audio signal. The response message converted into a signal is input to the second amplifier circuit (28) through the switch circuit (23), amplified, and then sent to the caller via the line transformer (4).Sending of the response message When the operation is completed, the control circuit (10) switches to a state in which a message from the caller is stored.When such a switching operation is performed, the second voice conversion circuit (22) and the response message memory circuit (17) becomes inactive, and the first voice conversion circuit (21) becomes active.Also, the first memory circuit (18) provided to store a message from the caller enters a writing operation state. In such a state, the message from the caller is transmitted through the line transformer (4) to the first amplifier circuit (
After being input to 14) and amplified, the switch circuit (15)
The signal is input to the first voice conversion circuit (21) through the voice converter circuit (21). The message from the caller that has been input into the first voice conversion circuit (21) is converted into a digital signal and then sent to the write terminal (18a) of the first memory circuit (18) which is in a writing state.
and is stored in the first memory circuit (18).

The message from the caller is memorized, and when a predetermined period of time has elapsed, that is, a period of time set in consideration of the capacity of the first memory circuit (18), the closing operation by the closing circuit (11) is released and the answering machine is released. The automatic response device returns to a state in which it performs automatic response operations. In this way, the automatic answering operation, that is, the operation of storing the message from the caller in the first memory circuit <18> after sending the response message to the caller, is performed, but the message from the caller for the next incoming call is The storage operation is performed by the second memory circuit (19), and the storage operation of the message from the caller for the next incoming call is performed by the third memory circuit (20).
It is carried out by When the message from the caller is stored in all the memory circuits, the control circuit (10
), even if a calling signal arrives, the closed circuit (1
1) does not operate, and in the case of a device equipped with a function to remotely listen to a message from a caller stored in a memory circuit, the time until the closing operation is performed is the normal operating time. It is also possible to switch to a longer length.

Although the automatic response operation is carried out as described above, the reproduction and listening operation of the message stored in this manner will now be explained.

Such reproduction listening operation is performed by closing the reproduction switch (7), and when the reproduction switch (7) is closed, a signal is output to the first output terminal (24) of the switch circuit (23). As soon as the second
The voice conversion circuit (22) becomes operational. Also, the first memory circuit (18) is in a state where it performs a read operation,
The message from the caller stored as a digital signal in the first memory circuit (18) is read out and input to the second voice conversion circuit (22). The message digital signal input to the second audio conversion circuit (22) is converted into an audio signal by the second audio conversion circuit (22), and then sent to the reproduction amplifier circuit (26) through the switch circuit (23>). The reproduction amplifier circuit (26
) is amplified and then applied to the speaker (27) to emit sound, so that the user can hear the message from the caller. Said first
When the playback switch (7) is closed again after the message stored in the memory circuit (18) has been played back and listened to, the first memory circuit (18) becomes inoperable due to the action of the control circuit (10). At the same time, the second memory circuit (19) enters a state where it performs a read operation,
The message stored in the second memory circuit (19) is emitted by the speaker (27) so that the message can be heard.Also, when the playback switch (7) is next closed, the second memory circuit (19) emits the message. 2 memory circuit (19)
becomes inoperable and the third memory circuit (20) enters a state where it performs a read operation, and the message stored in the third memory circuit (20) is transmitted to the speaker (2).
7>, so the message can be heard. Then, when the playback switch (7>) is closed, the third memory circuit (20) becomes inactive and the first memory circuit (17) becomes in a state where it performs the read operation. Each time the switch (7) is closed, the memory circuits that are in the reading operation state are switched in order, and the stored messages can be played back and listened to.Then, the playback operation of the messages stored in each memory circuit is performed. If you close the playback switch (7) while the message is in progress, the message stored in the next memory circuit will be immediately played back, making it very convenient to listen to the message from the desired caller. It's convenient.

Although the reproduction/listening operation of the message from the caller stored in each memory circuit can be carried out as described above, the erasing operation will now be explained. Such a message erasing operation is performed by closing the erasing switch (8) while the message stored in each memory circuit is being played back and listened to. For example, if the erasing switch (8) is closed while a message stored in the first memory circuit (18) is being played back, the control circuit (10) A signal for performing an erase operation is output to the erase terminal (18d), and the message stored in the first memory circuit (18>) is erased.In this way, the erase operation of the first memory circuit (18) is performed. However, since the erasing operation of the second memory circuit (19) and the third memory circuit (20) is also performed in the same manner, the explanation thereof will be omitted.

As described above, each operation in this embodiment is performed, but
Next, an explanation will be given of a call recording operation in which the user records the voice of the caller while the user is talking with the caller. This is done by closing the call recording switch (9) while the user is talking to the caller.

When the call recording switch (9) is closed, the control circuit (10) causes the switch circuit (15) to output the signal from the first amplifier circuit (14), and also outputs the signal from the first audio conversion circuit (14). 21) becomes operational.Furthermore, the first memory circuit (18), the second memory circuit (19), and the third memory circuit (20) enter a state in which they continuously store messages from the caller. Become. The voice from the caller inputted through the line transformer (4) is inputted to the first amplifier circuit (14) and amplified, and then applied to the first voice conversion circuit (21) through the switch circuit (15) to convert it into a digital signal. is converted to The audio signal converted into a digital signal by the first audio conversion circuit (21) is sent to a write terminal provided in the first memory circuit (18), the second memory circuit (19), and the third memory circuit (20). (18a), (19a), (20
a) is applied. The control circuit (10) then starts the storage operation from the first memory circuit (18), and when the capacity of the first memory circuit (18) is stored, the second memory circuit (19) becomes operational. The first
The continuation of the audio stored in the memory circuit (18) can be stored in the second memory circuit (19). Furthermore, when the capacity of the second memory circuit (19) is stored, the capacity of the third memory circuit (19) is stored.
20) becomes operational, and its continuation is stored in the third memory circuit (20). In this way, during the call recording operation, the first memory circuit (18), the second memory circuit (19), and the third memory circuit (20) are continuously used as memory circuits, so that long-term memory operation can be performed. I can do it. The call recording operation is performed in this manner, and next, the reproduction operation of the message stored by such operation will be explained. When the playback switch (7) is closed after such a call recording operation is performed, a signal is output to the first output terminal (24) of the switch circuit (23) and the second audio conversion circuit (22) is output.
) becomes operational. When in such a reproduction operation state, the messages stored in the first memory circuit (18), second memory circuit (19), and third memory circuit (20) are read out continuously, and the messages are read out by the user. The caller's message recorded during the call can be played back and listened to by the sound emitting operation of the speaker (27).

In the Naoki embodiment, the number of memory circuits for storing the caller's message as a digital signal is three, but the number is not limited.

(G) Effects of the Invention The present invention provides a reading operation every time a reproduction switch is operated, which can create a reproduction operation state for messages stored in a plurality of received message memory circuits provided corresponding to each call. Since the memory circuits where the messages are carried out are switched one after another in sequence, the parts of the memory circuits where unnecessary messages such as prank calls are stored are
Since it is possible to switch to the next memory circuit immediately after reproducing the beginning part, this is very effective when reproducing and listening to a message from a desired caller.
